BACKGROUND

Technical Field

This disclosure relates to inhibitors of one or more proteins in the Wnt pathway, including inhibitors of one or more Wnt proteins, and compositions comprising the same. More particularly, it concerns the use of an isoquinoline compound or salts or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis, Alzheimer's disease, lung disease, inflammation, auto-immune diseases fibrotic disorders, cartilage (chondral) defects, and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as genetic diseases and neurological conditions/disorders/diseases due to mutations or dysregulation of the Wnt pathway and/or of one or more of Wnt signaling components. Also provided are methods for treating Wnt-related disease states, as well as neurological conditions/disorders/diseases linked to overexpression of DYRK1A.

Background

The Wnt growth factor family includes more than 10 genes identified in the mouse and at least 19 genes identified in the human. Members of the Wnt family of signaling molecules mediate many short- and long-range patterning processes during invertebrate and vertebrate development. The Wnt signaling pathway is known for its role in the inductive interactions that regulate growth and differentiation, and it also plays roles in the homeostatic maintenance of post-embryonic tissue integrity. Wnt stabilizes cytoplasmic β-catenin, which stimulates the expression of genes including c-myc, c jun, fra-1, and cyclin D1. In addition, misregulation of Wnt signaling can cause developmental defects and is implicated in the genesis of several human cancers. The Wnt pathway has also been implicated in the maintenance of stem or progenitor cells in a growing list of adult tissues including skin, blood, gut, prostate, muscle, and the nervous system.

Dual specificity tyrosine-phosphorylation-regulated kinase 1A is an enzyme that in humans is encoded by the DYRK1A gene. DYRK1A is a member of the dual-specificity tyrosine phosphorylation-regulated kinase (DYRK) family. DYRK1A contains a nuclear targeting signal sequence, a protein kinase domain, a leucine zipper motif, and a highly conservative 13-consecutive-histidine repeat. It catalyzes its autophosphorylation on serine/threonine and tyrosine residues. It may play a significant role in a signaling pathway regulating cell proliferation and may be involved in brain development. DYRK1A is localized in the Down syndrome critical region of chromosome 21, and is considered to be a candidate gene for learning defects associated with Down syndrome. DYRK1A is also expressed in adult brain neurons, indicating that DYRK1A may play a role in the mature central nervous system. Thus, several lines of evidence point to some synaptic functions of DYRK1A. For instance, it has been found that DYRK1A phosphorylates and modulates the interaction of several components of the endocytic protein complex machinery (Dynamin 1, Amphiphysin, and Synaptojanin), suggesting a role in synaptic vesicle recycling. In addition, a polymorphism (SNP) in DYRK1A was found to be associated with HIV-1 replication in monocyte-derived macrophages, as well as with progression to AIDS in two independent cohorts of HIV-1-infected individuals.

A “therapeutically effective amount” of a compound as provided herein is one which is sufficient to achieve the desired physiological effect and may vary according to the nature and severity of the disease condition, and the potency of the compound. “Therapeutically effective amount” is also intended to include one or more of the compounds of Formula I in combination with one or more other agents that are effective to treat the diseases and/or conditions described herein. The combination of compounds can be a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Advances in Enzyme Regulation (1984), 22, 27-55, occurs when the effect of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. It will be appreciated that different concentrations may be employed for prophylaxis than for treatment of an active disease. This amount can further depend upon the patient's height, weight, sex, age and medical history.

A therapeutic effect relieves, to some extent, one or more of the symptoms of the disease.

“Treat,” “treatment,” or “treating,” as used herein refers to administering a compound or pharmaceutical composition as provided herein for therapeutic purposes.

It is to be further understood that for any particular patient, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed compositions.

In one embodiment, the compositions can be administered to the respiratory tract (including nasal and pulmonary) e.g., through a nebulizer, metered-dose inhalers, atomizer, mister, aerosol, dry powder inhaler, insufflator, liquid instillation or other suitable device or technique.

In some embodiments, aerosols intended for delivery to the nasal mucosa are provided for inhalation through the nose. For optimal delivery to the nasal cavities, inhaled particle sizes of about 5 to about 100 microns are useful, with particle sizes of about 10 to about 60 microns being preferred. For nasal delivery, a larger inhaled particle size may be desired to maximize impaction on the nasal mucosa and to minimize or prevent pulmonary deposition of the administered formulation. In some embodiments, aerosols intended for delivery to the lung are provided for inhalation through the nose or the mouth. For delivery to the lung, inhaled aerodynamic particle sizes of about less than 10 μm are useful (e.g., about 1 to about 10 microns). Inhaled particles may be defined as liquid droplets containing dissolved drug, liquid droplets containing suspended drug particles (in cases where the drug is insoluble in the suspending medium), dry particles of pure drug substance, drug substance incorporated with excipients, liposomes, emulsions, colloidal systems, coacervates, aggregates of drug nanoparticles, or dry particles of a diluent which contain embedded drug nanoparticles.

In some embodiments, compounds of Formula (I) disclosed herein intended for respiratory delivery (either systemic or local) can be administered as aqueous formulations, as non-aqueous solutions or suspensions, as suspensions or solutions in halogenated hydrocarbon propellants with or without alcohol, as a colloidal system, as emulsions, coacervates, or as dry powders. Aqueous formulations may be aerosolized by liquid nebulizers employing either hydraulic or ultrasonic atomization or by modified micropump systems (like the soft mist inhalers, the Aerodose® or the AERx® systems). Propellant-based systems may use suitable pressurized metered-dose inhalers (pMDIs). Dry powders may use dry powder inhaler devices (DPIs), which are capable of dispersing the drug substance effectively. A desired particle size and distribution may be obtained by choosing an appropriate device.

In some embodiments, the compositions of Formula (I) disclosed herein can be administered to the ear by various methods. For example, a round window catheter (e.g., U.S. Pat. Nos. 6,440,102 and 6,648,873) can be used.

Alternatively, formulations can be incorporated into a wick for use between the outer and middle ear (e.g., U.S. Pat. No. 6,120,484) or absorbed to collagen sponge or other solid support (e.g., U.S. Pat. No. 4,164,559).

If desired, formulations of the disclosure can be incorporated into a gel formulation (e.g., U.S. Pat. Nos. 4,474,752 and 6,911,211).

In some embodiments, compounds of Formula (I) disclosed herein intended for delivery to the ear can be administered via an implanted pump and delivery system through a needle directly into the middle or inner ear (cochlea) or through a cochlear implant stylet electrode channel or alternative prepared drug delivery channel such as but not limited to a needle through temporal bone into the cochlea.

Other options include delivery via a pump through a thin film coated onto a multichannel electrode or electrode with a specially imbedded drug delivery channel (pathways) carved into the thin film for this purpose. In other embodiments the acidic or basic solid compound of Formula (I) can be delivered from the reservoir of an external or internal implanted pumping system.

Formulations of the disclosure also can be administered to the ear by intratympanic injection into the middle ear, inner ear, or cochlea (e.g., U.S. Pat. No. 6,377,849 and Ser. No. 11/337,815).

Intratympanic injection of therapeutic agents is the technique of injecting a therapeutic agent behind the tympanic membrane into the middle and/or inner ear. In one embodiment, the formulations described herein are administered directly onto the round window membrane via transtympanic injection. In another embodiment, the ion channel modulating agent auris-acceptable formulations described herein are administered onto the round window membrane via a non-transtympanic approach to the inner ear. In additional embodiments, the formulation described herein is administered onto the round window membrane via a surgical approach to the round window membrane comprising modification of the crista fenestrae cochleae.

In some embodiments, the compounds of Formula (I) are formulated in rectal compositions such as enemas, rectal gels, rectal foams, rectal aerosols, suppositories, jelly suppositories, or retention enemas, containing conventional suppository bases such as cocoa butter or other glycerides, as well as synthetic polymers such as polyvinylpyrrolidone, PEG (like PEG ointments), and the like.

Suppositories for rectal administration of the drug (either as a solution, colloid, suspension or a complex) can be prepared by mixing a compound provided herein with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt or erode/dissolve in the rectum and release the compound. Such materials include cocoa butter, glycerinated gelatin, hydrogenated vegetable oils, poloxamers, mixtures of polyethylene glycols of various molecular weights and fatty acid esters of polyethylene glycol. In suppository forms of the compositions, a low-melting wax such as, but not limited to, a mixture of fatty acid glycerides, optionally in combination with cocoa butter, is first melted.

Solid compositions can be provided in various different types of dosage forms, depending on the physicochemical properties of the compound provided herein, the desired dissolution rate, cost considerations, and other criteria. In one of the embodiments, the solid composition is a single unit. This implies that one unit dose of the compound is comprised in a single, physically shaped solid form or article. In other words, the solid composition is coherent, which is in contrast to a multiple unit dosage form, in which the units are incoherent.

Examples of single units which may be used as dosage forms for the solid composition include tablets, such as compressed tablets, film-like units, foil-like units, wafers, lyophilized matrix units, and the like. In one embodiment, the solid composition is a highly porous lyophilized form. Such lyophilizates, sometimes also called wafers or lyophilized tablets, are particularly useful for their rapid disintegration, which also enables the rapid dissolution of the compound.

On the other hand, for some applications the solid composition may also be formed as a multiple unit dosage form as defined above. Examples of multiple units are powders, granules, microparticles, pellets, mini-tablets, beads, lyophilized powders, and the like. In one embodiment, the solid composition is a lyophilized powder. Such a dispersed lyophilized system comprises a multitude of powder particles, and due to the lyophilization process used in the formation of the powder, each particle has an irregular, porous microstructure through which the powder is capable of absorbing water very rapidly, resulting in quick dissolution. Effervescent compositions are also contemplated to aid the quick dispersion and absorption of the compound.

Another type of multiparticulate system which is also capable of achieving rapid drug dissolution is that of powders, granules, or pellets from water-soluble excipients which are coated with a compound provided herein so that the compound is located at the outer surface of the individual particles. In this type of system, the water-soluble low molecular weight excipient may be useful for preparing the cores of such coated particles, which can be subsequently coated with a coating composition comprising the compound and, for example, one or more additional excipients, such as a binder, a pore former, a saccharide, a sugar alcohol, a film-forming polymer, a plasticizer, or other excipients used in pharmaceutical coating compositions.

Also provided herein are kits. Typically, a kit includes one or more compounds or compositions as described herein. In certain embodiments, a kit can include one or more delivery systems, e.g., for delivering or administering a compound as provided herein, and directions for use of the kit (e.g., instructions for treating a patient). In another embodiment, the kit can include a compound or composition as described herein and a label that indicates that the contents are to be administered to a patient with cancer. In another embodiment, the kit can include a compound or composition as described herein and a label that indicates that the contents are to be administered to a patient with one or more of hepatocellular carcinoma, colon cancer, leukemia, lymphoma, sarcoma, ovarian cancer, diabetic retinopathy, pulmonary fibrosis, rheumatoid arthritis, sepsis, ankylosing spondylitis, psoriasis, scleroderma, mycotic and viral infections, bone and cartilage diseases, Alzheimer's disease, lung disease, bone/osteoporotic (wrist, spine, shoulder and hip) fractures, articular cartilage (chondral) defects, degenerative disc disease (or intervertebral disc degeneration), polyposis coli, bone density and vascular defects in the eye (Osteoporosis-pseudoglioma Syndrome, OPPG), familial exudative vitreoretinopathy, retinal angiogenesis, early coronary disease, tetra-amelia, Müllerian-duct regression and virilization, SERKAL syndrome, type II diabetes, Fuhrmann syndrome, Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome, odonto-onycho-dermal dysplasia, obesity, split-hand/foot malformation, caudal duplication, tooth agenesis, Wilms tumor, skeletal dysplasia, focal dermal hypoplasia, autosomal recessive anonychia, neural tube defects, alpha-thalassemia (ATRX) syndrome, fragile X syndrome, ICF syndrome, Angelman syndrome, Prader-Willi syndrome, Beckwith-Wiedemann Syndrome, Norrie disease, and Rett syndrome.

Evaluation of Biological Activity

The biological activity of the compounds described herein can be tested using any suitable assay known to those of skill in the art, see, e.g., WO 2001/053268 and WO 2005/009997. For example, the activity of a compound may be tested using one or more of the test methods outlined below.

In one example, tumor cells may be screened for Wnt independent growth. In such a method, tumor cells of interest are contacted with a compound (i.e. inhibitor) of interest, and the proliferation of the cells, e.g. by uptake of tritiated thymidine, is monitored. In some embodiments, tumor cells may be isolated from a candidate patient who has been screened for the presence of a cancer that is associated with a mutation in the Wnt signaling pathway. Candidate cancers include, without limitation, those listed above.

In another example, one may utilize in vitro assays for Wnt biological activity, e.g. stabilization of β-catenin and promoting growth of stem cells. Assays for biological activity of Wnt include stabilization of β-catenin, which can be measured, for example, by serial dilutions of a candidate inhibitor composition. An exemplary assay for Wnt biological activity contacts a candidate inhibitor with cells containing constitutively active Wnt/β-catenin signaling. The cells are cultured for a period of time sufficient to stabilize β-catenin, usually at least about 1 hour, and lysed. The cell lysate is resolved by SDS PAGE, then transferred to nitrocellulose and probed with antibodies specific for β-catenin.

In a further example, the activity of a candidate compound can be measured in a Xenopus secondary axis bioassay (Leyns, L. et al. Cell (1997), 88(6), 747-756).

In another example, in vitro assays for DYRK1A biological activity may be used, e.g. regulation of microtubule-associated protein tau (MAPT/Tau) phosphorylation in neuronal cell line such as the human SH-SY5Y neuroblastoma cell line. Assays for DYRK1A-regulated level of phosphorylation can include monitoring levels of basal pSer396 Tau, which can be measured, for example, by serial dilutions of a candidate inhibitor composition using a ten micromolar top concentration and detected by ELISA or Western Blotting. An exemplary assay for DYRK-1A-regulated phosphorylation uses the SH-SY5Y cells cultured in a 96 well plate format for a period of time sufficient to stabilize microtubules and Tau phosphorylation, usually at least 2 days, then treated with a 1/3 serial dilution of compounds overnight and lysed. The cell lysate is resolved by SDS PAGE, then transferred to nitrocellulose and probed with an antibody specific for pSer396 Tau. The chemiluminescence signal for HRP-linked antibodies used in western blotting is detected using a Carestream Image Station and blot densitometry for pSer396 and beta-actin are analyzed using ImageJ (NIH).

In a further example, the activity of a candidate compound can be measured by ELISA by adding the lysate mentioned above onto total Tau-coated plates and detected with a specific pSer396 antibody. Colorimetric detection of ELISA signal is performed by Cytation3 plate reader (Biotek).

General Procedures

Compounds of Formula I of the present disclosure can be prepared as depicted in Scheme 1.

Scheme 1 describes a method for preparation of isoquinoline-3-carboxamide derivatives (IX) by first coupling the amine with a variety of acids (III) to produce amide IV.

Example 13

The screening assay for Wnt activity is described as follows. Reporter cell lines can be generated by stably transducing cancer cell lines (e.g., colon cancer) or primary cells (e.g., IEC-6 intestinal cells) with a lentiviral construct that includes a Wnt-responsive promoter driving expression of the firefly luciferase gene.

SW480 colon carcinoma cells were transduced with a lentiviral vector expressing luciferase with a human Sp5 promoter consisting of a sequence of eight TCF/LEF binding sites. SW480 cells stably expressing the Sp5-Luc reporter gene and a hygromycin resistance gene were selected by treatment with 150 μg/mL of hygromycin for 7 days. These stably transduced SW480 cells were expanded in cell culture and used for all further screening activities. Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 10-point dose-response curves starting from 10 μM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well white solid bottom assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.1%. For Sp5-Luc reporter gene assays, the cells were plated at 4,000 cells/well in 384-well plates with a DMEM medium containing 1% fetal bovine serum, and 1% Penicillin-Streptomycin and incubated for 36 to 48 hours at 37° C. and 5% CO₂. Following incubation, 15 μl of BriteLite Plus luminescence reagent (Perkin Elmer) was added to each well of the 384-well assay plates. The plates were placed on an orbital shaker for 2 min and then luminescence was quantified using the Envision (Perkin Elmer) plate reader. Readings were normalized to DMSO only treated cells, and normalized activities were utilized for EC₅₀ calculations using the dose-response log (inhibitor) vs. response-variable slope (four parameters) nonlinear regression feature available in GraphPad Prism 5.0 (or Dotmatics).

Example 14

Representative compounds were screened using the assay procedure for DYRK1A kinase activity as described below.

Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 11-point dose-response curves from 10 μM to 0.00016 μM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 1536-well black-walled round bottom plates (Corning).

The DYRK1A kinase assay was run using the Ser/Thr 18 peptide Z-lyte assay kit according to manufacturer's instructions (Life Technologies—a Division of Thermo-Fisher). This is a non-radioactive assay using fluorescence resonance energy transfer (FRET) between coumarin and fluorescein to detect kinase activity which is represented as a ratio of coumarin emission/fluorescein emission.

Briefly, recombinant DYRK1A kinase, ATP and Ser/Thr peptide 18 were prepared in 1× Kinase buffer to final concentrations of 0.19 μg/mL, 30 μM, and 4 μM respectively. The mixture was allowed to incubate with the representative compounds for one hour at room temperature. All reactions were performed in duplicate. Unphosphorylated (“0% Control”) and phosphorylated (“100% control”) forms of Ser/Thr 18 served as control reactions. Additionally, an 11-point dose-response curve of Staurosporine (1 μM top) was run to serve as a positive compound control.

After incubation, Development Reagent A was diluted in Development Buffer then added to the reaction and allowed to further incubate for one hour at room temperature. The plate was read at Ex 400 Em 455 to detect the coumarin signal and Ex 400 Em 520 to measure the signal (EnVision Multilabel Plate Reader, PerkinElmer).

The Emission ratio (Em) was calculated as a ratio of the coumarin (C) emission signal (at 445 nm)/Fluorescein (F) emission signal (at 520 nm). The percent phosphorylation was then calculated using the following formula: [1−((Em ratio×F100%)−C100%)/((C0%−C100%)+(Em ratio×(F100%−F0%)))]. Dose-response curves were generated and inhibitory concentration (IC₅₀) values were calculated using non-linear regression curve fit in the Dotmatics' Studies Software (Bishops Stortford, UK).

Example 16

Representative compounds were screened using the assay procedure for tau phosphorylation activity described below.

SH-SY5Y cells (human neuroblastoma) were cultured in DMEM/F-12 medium supplemented with 15% FBS, Non-essential Amino Acid and Penicillin/Streptomycin. Two days before treatment, cells were seeded onto 96 well plates at 5×10⁴ cells/well.

The above synthesized compounds were screened using the cell assay procedure to assess decrease Tau phosphorylation at Ser396 (pSer396) described below.

DMSO-resuspended compounds were dispensed to 8 wells as a serial titration from 10 μM to 4.6 nM final in medium and cells were exposed overnight (16-18 h) in a humidified incubator at 36.6c before harvest. Wells were visually checked for cell death or change in morphology and supernatants were tested for cytotoxicity by measurement of lactate dehydrogenase release (LDH, CytoToxOne kit, Promega) if necessary. As controls, commercially available DYRK1A inhibitors, Harmine and Indy which were shown to have good DYRK1A inhibition in the kinase assay with no CDK1 activity (EC₅₀ 18 and 53 nM respectively, 6 μM for CDK1) but weak EC₅₀ in the Tau assay >10 M.

Cells were lysed with RIPA buffer complemented with phosphatase and protease inhibitors then lysates were spun down at 12,000 g for 10 min to remove any cellular debris. Lysates are then either directly tested for pSer396 by ELISA (Life Technology, Kit KHB7031) or loaded on NuPage Bis-Tris gels for western blot analysis. Colorimetric detection of ELISA signal is performed by Cytation3 plate reader (Biotek) and the chemiluminescence signal for HRP-linked antibodies used in western blotting is detected using a Carestream Image Station. The same pSer396 antibody is used for detection of pTau in both assays.

Blot densitometry for pSer396 and β-actin were analyzed using ImageJ (NIH) and pSer396 Tau ELISA signal was used to plot, draw the curve fitting, and determine each compounds EC₅₀ in Prism (GraphPad).

Example 17

Representative compounds were screened using the cell-based assay procedure for secreted β-amyloid 40 (Aβ40) peptide in an APP overexpressing cell line described below.

SH-SY5Y cells (human neuroblastoma) were cultured in 1:1 DMEM/F-12 medium supplemented with 15% FBS, 1% non-essential amino acids, and 1% penicillin/streptomycin. HEK293T cells (human kidney) were cultured in DMEM medium supplemented with 10% FBS and 1% penicillin/streptomycin.

SH-SY5Y cells were infected with lentivirus to overexpress amyloid (A4) beta precursor protein (APP), hereafter referred to as the SH-SY5Y-APP cells. Specifically, in a 10 cm dish, HEK293T cells were seeded at 2.5×10⁵

$\frac{cells}{mL}$ and transfected with APP (Myc-DDK-tagged)-Human amyloid beta (A4) precursor protein (APP), transcript variant 3 pLenti-ORF expression construct (custom modification of RC215147 to include bicistronic IRES-puromycin, OriGene). Culture medium was changed 18 h post-transfection before a first batch of viral supernatant was then harvested at 42 h post-transfection. Culture medium was replenished once more before a second batch of viral supernatant was harvested 66 h post-transfection. The two batches of viral supernatant were combined and spun at 1800 g, then filtered through a 0.45 μm PVDF filter.

SH-SY5Y cells were seeded onto 6-well plates at 5.0×10⁵

$\frac{cells}{well}$ and incubated overnight at 37° C. Cells were then infected with viral supernatant at concentrations ranging from 10%→100% viral supernatant (diluted in Opti-MEM as appropriate), with 10

$\frac{µg}{mL}$ Polybrene added for permeability (H9268, Sigma). 24 hours post-transfection, the entire volume from each well was replaced with regular SH-SY5Y medium. 4 days post-transfection, APP-overexpressing SH-SY5Y cells were selected for by adding puromycin (A11138-03, Gibco) to each well at a final concentration of 2

$\frac{µg}{mL}.$ Puromycin-resistant cell were then expanded, harvested and banked. APP-overexpression was controlled by immunoblotting for total APP and Myc-DDK.

The cell assay procedure start 18 h prior to treatment, as SH-SY5Y-APP cells were seeded onto 96-well plates at 2.0×10⁴

$\frac{cells}{well}.$ The entire 200 μL volume of medium was removed well from all wells, and replenished to reset any Aβ40 peptide that may have been secreted prior to treatment. DMSO-resuspended compounds were dispensed to eight wells as a serial dilution from 10 μM to 4.6 nM final concentration in medium. At this time, designated wells were seeded with SH-SY5Y cells that were seeded and treated with puromycin at 10

$\frac{µg}{mL}.$ Cells were exposed overnight (16-18 hours) in a 37° C. incubator before supernatant was harvested. Wells were visually checked for cell death before 150 μL of supernatant was harvested from each well into V-bottom 96-well plates (3894, Corning). The original plates with seeded cells were tested for cytotoxicity by measure of adenosine triphosphate (ATP) release by adding CellTiter-Glo® diluted 1:4 in distilled water (G7573, Promega) and transferring lysed cells to a completely black 96-well plate to be read with the Cytation3. Plates containing supernatant were spun down at 1200 g for 10 minutes to remove any cellular debris. Supernatant was then diluted 1:2 with a diluent from V-PLEX Aβ40 Peptide (6E10) Kit and directly tested for secreted Aβ40 peptide (K150SKE, Meso Scale Discovery). The signal was used to plot, draw the curve fitting, and determine each compounds EC₅₀ in Prism (GraphPad).

Representative compounds were screened using the assay procedure to assess the effect on cell viability as described below.

SW480 colon carcinoma cells were transduced with a lentiviral vector expressing luciferase with a human Sp5 promoter consisting of a sequence of eight TCF/LEF binding sites. SW480 cells stably expressing the Sp5-Luc reporter gene and a hygromycin resistance gene were selected by treatment with 150 μg/mL of hygromycin for 7 days. These stably transduced SW480 cells were expanded in cell culture and used for all further screening activities. Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 8-point dose-response curves from 10 μM to 0.0045 μM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well white solid bottom assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.1%.

For the Cell Viability Assays, the cells were plated at 2,000 cells/well in 384-well plates with a DMEM medium containing 1% fetal bovine serum, and 1% Penicillin-Streptomycin and incubated for four days hours at 37° C. and 5% CO₂. Eight replicates of DMSO-treated cells served as controls and cells treated with compound were performed in duplicate.

After incubation, 10 μL of CellTiter-Glo (Promega) was added to each well allowed to incubate for approximately 12 minutes. This reagent “results in cell lysis and generation of a luminescent signal proportional to the amount of ATP present. The amount of ATP is directly proportional to the number of cells present in culture, in agreement with previous reports. The CellTiter-Glo® Assay generates a “glow-type” luminescent signal, produced by the luciferase reaction (Promega.com)”.

After incubation, the plates were read at Ex 560 nm Em 590 nm (Cytation 3, BioTek). Dose-response curves were generated and EC₅₀ concentration values were calculated using non-linear regression curve fit in the GraphPad Prism (San Diego, Calif.) or Dotmatics' Studies Software (Bishops Stortford, UK). For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.

Representative compounds were screened using primary human fibroblasts (derived from IPF patients) treated with TGF-β1 to determine their ability to inhibit the fibrotic process.

Human Fibroblast Cell Culture: Primary human fibroblasts derived from IPF patients (LL29 cells) [¹Xiaoqiu Liu, et. al., “Fibrotic Lung Fibroblasts Show Blunted Inhibition by cAMP Due to Deficient cAMP Response Element-Binding Protein Phosphorylation”, Journal of Pharmacology and Experimental Therapeutics (2005), 315(2), 678-687; ²Watts, K. L., et. al., “RhoA signaling modulates cyclin D1 expression in human lung fibroblasts; implications for idiopathic pulmonary fibrosis”, Respiratory Research (2006), 7(1), 88] were obtained from American Type Culture Collection (ATCC) and expanded in F12 medium supplemented with 15% Fetal Bovine Serum and 1% Penicillin/Streptomycin.

Compound Screening: Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:2, 11-point dose-response curves from 10 M to 0.94 nM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well clear bottom assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.1%. LL29 cells were plated at 1,500 cells/well in 70 μL/well F12 medium supplemented with 1% Fetal Bovine Serum. TGF-β1 (Peprotech; 20 ng/mL) was added to the plates to induce fibrosis (ref. 1 and 2 above). Wells treated with TGF-β1 and containing DMSO were used as positive control, and cells with only DMSO were negative control. Cells were incubated at 37° C. and 5% CO₂ for 4 days. Following incubation for 4 days, SYTOX green nucleic acid stain (Life Technologies [Thermo Fisher Scientific]) was added to the wells at a final concentration of 1 μM and incubated at room temperature for 30 min. Cells were then fixed using 4% formaldehyde (Electron Microscopy Sciences), washed 3 times with PBS followed by blocking and permeabilization using 3% Bovine Serum Albumin (BSA; Sigma) and 0.3% Triton X-100 (Sigma) in PBS. Cells were then stained with antibody specific to α-smooth muscle actin (αSMA; Abcam) (ref. 1 and 2 above) in 3% Bovine Serum Albumin (BSA; Sigma) and 0.3% Triton X-100 (Sigma) in PBS, and incubated overnight at 4° C. Cells were then washed 3 times with PBS, followed by incubation with Alexa Flor-647 conjugated secondary antibody (Life Technologies [Thermo Fisher Scientific]) and DAPI in 3% Bovine Serum Albumin (BSA; Sigma) and 0.3% Triton X-100 (Sigma) in PBS at room temperature for 1 hour. Cells were then washed 3 times with PBS and plates were sealed for imaging. αSMA staining was imaged by excitation at 630 nm and emission at 665 nm and quantified using the Compartmental Analysis program on the CellInsight CX5 (Thermo Scientific). Dead or apoptotic cells were excluded from analysis based on positive SYTOX green staining. % of total cells positive for αSMA were counted in each well and normalized to the average of 11 wells treated with TGF-β1 on the same plate using Dotmatics' Studies Software. The normalized averages (fold change over untreated) of 3 replicate wells for each compound concentration were used to create dose-responses curves and EC₅₀ values were calculated using non-linear regression curve fit in the Dotmatics' Studies Software. For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.

Representative compounds were screened using the following assay procedure to determine their ability to inhibit IL-6 and therefore demonstrate their anti-inflammatory properties.

Human Peripheral Blood Mononuclear Cells: Fresh Normal PB MNC (Catalog # PB001, AllCells, Alameda, Calif.) were shipped overnight at 4° C. and resuspended in Roswell Park Memorial Institute (RPMI) 1640 Medium, with GlutaMAX Supplement (Catalog #61870127, ThermoFisher Scientific, Waltham, Mass.) supplemented with 1% Penicillin-Streptomycin (Catalog#15140163, ThermoFisher Scientific, Waltham, Mass.) and 1% fetal bovine serum (FBS) (Catalog #16140089, ThermoFisher Scientific, Waltham, Mass.) assay media.

Compound Screening: Fresh normal human peripheral blood mononuclear cells (huPBMCs) were resuspended in 1% FBS-RPMI assay media with 1% Penicillin-Streptomycin 1% to a cell concentration of 1×10e6 cells/mL. Each compound was dissolved in DMSO (Catalog # D8418-100 ml, Sigma-Aldrich, St. Louis, Mo.) as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 10-point dose-response curves starting from 10 μM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well white Proxiplate-Plus assay plates (Catalog #6008289, PerkinElmer, Shelton, Conn.) with appropriate DMSO backfill for a final DMSO concentration of 0.25%. huPBMCs were plated at 5000 cells/well in the 384-well Proxiplate-Plus assay plates and incubated at 37° C.-5% CO₂ for 2 hours. 50 ng/mL of Lipopolysaccharides from Escherichia coli 0111:B4 (Catalog #L5293-2ML, Sigma-Aldrich, St. Louis, Mo.) was added after 2 hours and cells were incubated for another 22 hours at 37° C.-5% CO₂. After 22 hour incubation, a mixture of anti-IL6 XL665 and anti-IL-6 Cryptate diluted in reconstitution buffer (Catalog #62IL6PEC, Cisbio Inc., Bedford, Mass.) was added to each well. Following incubation for 3 hours at room temperature, Homogeneous Time-Resolved Fluorescence (HTRF) was measured using the Envision (Perkin Elmer, Shelton, Conn.) at 665 nm and 620 nM. The ratio of fluorescence at 665 nm to 620 nm was used as a readout for IL-6 quantification. All samples were processed in duplicate. Readings were normalized to DMSO treated cells and normalized activities were utilized for EC₅₀ calculations. EC₅₀ was determined using software generated by Dotmatics Limited (Windhill Bishops Stortford Herts, UK) using the Levenberg-Marquardt 4 parameter fitting procedure with finite different gradients. For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.

Example 21

Representative compounds were screened using the cell-based assay procedure for secreted cytokines in a Lipopolysaccharide-stimulated mouse glial cell line described below.

BV-2 cells (mouse microglial cells) were cultured in 1:1 DMEM medium supplemented with 10% FBS, and 1% penicillin/streptomycin.

Compound Screening: BV-2 cells are plated at 35,000 cells/well in a volume of 100 ul for at least 4 hours before compounds are added. DMSO-resuspended compounds were first dispensed in a 96 well plate and serial diluted from 10 μM to 4.6 nM final concentration in medium. Compounds were added to cells overnight. Two hundred fifty ng per milliliter of lipopolysaccharide (Escherichia coli 055:B5, SIGMA) was added for 5 h. Supernatant is removed and saved for further cytokine detection. The original plates with seeded cells were tested for cytotoxicity by measure of adenosine triphosphate (ATP) release by adding CellTiter-Glo diluted 1:4 in distilled water (G7573, Promega) and transferring lysed cells to a completely black 96-well plate to be read with the Cytation3. Supernatant was then diluted 1:2 with a diluent from V-PLEX cytokine Kit and directly tested for the secreted cytokines TNFα, IL-6 and KC-GRO using electrochemiluminescence (Meso Scale Discovery). The standard curve for each cytokine was used to convert the electrochemiluminescent signal into pg of protein per mL. The signal was used to plot, draw the curve fitting, and determine each compounds EC₅₀ in Prism (GraphPad).
